All other nationalities die off the face of planet Earth leaving just Asians, will there be harmony and peace?

Let’s say by some random and strange phenomenon, every other race and nationality other than Asian (Pacific Islanders are left as well) die off the planet Earth in a two week time frame, would there be peace, will harmony flourish? With no one left but them would they in time (or right away) start to discriminate among themselves? If they started drawing ranks, or kept up walls they have now, who would end up as top dog, and who would end up as the mutts of the doghouse?
